SWING.

Specification of Letters Patent.

Patented May 21, 191.6.

Application filed January 10, 1917. Serial No. 141,590.

To all whom it may concern:

Be it known that I, J OI-IN S.VWORZALLA, a citizen of the United States,and a resident of Stevens Point, in the county of Portage and State ofWisconsin, have invented a new and Improved Swing, of which the followinis a full, clear, and exact description.

y invention relates to a swing of the type in which the seat issupported on hangers mountedto swing in a foldable frame.

The general object of the invention is to provide a reversible seatformed of variously connected elements carried by the hangers andarranged so that the seat may be positioned at either side of thehangers.

Further objects of the invention are to provide in connection with thereversible seat, novel means to firmly sustain the same in eitherposition; and to provide a construction that will permit of the seatelements being folded within the plane of the hangers so that the swingwhen folded will occupy the minimum space.

The invention will be particularly explained in the specific descriptionfollowing.

Reference is to be had to the accompanying drawings forming apart ofthis specification in which similar reference characters indicatecorresponding parts in all the views.

Figure 1 is a perspective view of a swing embodying my invention;

Fig. 2 is a transverse vertical section of the folded swing;

Fig. 3 is a sectional side elevation of the seat and a portion of thehangers;

Fig. 4 is a view similar to Fig. 3 but showin the seat reversed;

ig. 5 is a face view of plates for the seat;

Fig. 6 is a detail in side elevation showing a novel buffer applicableto the legs at the one of the stop bottom thereof to prevent creeping ofthe form. The side frames or legs are pivotally connected at their upperends by eye-bolts 14, whereby one side frame may swing within the otherto lie in the same plane. Hanger bars 16 are suspended in the supportingframe preferably through the medium of eyes 15 engaging the eye-bolts14. The hangers 16 may be connected by cross bars 17 near the top.

The numeral 18 indicates the bottom or seat proper and 19 the backthereof. The side bars 20 of the seat 18 are pivotally connected neartheir front ends with the lower ends of the hangers 16 by pins or bolts22, and the rear ends of said side bars 20 are I pivotally connected asat 22 with the lower ends of the side posts 21 of the back. Arms 23 arepivotally connected at the forward ends with the hangers 16 above thepivots 22 of the seat 18, the said arms and said seat being disposedbetween the respective hangers. The rear ends of the arms 23 arepivotally connected with the upper ends of the to receive screws forsecuring the plate to the adjacent arm 23 to swing with the latter. ,Thenumeral 27 indicates the pivotal conner sides thereof below andapproximately in alinement with the pivots 26. Said stops 28 may be inthe form of screws as indicated.

By the described arrangement, the seat 18 and the arms 23 may have apivotal movement fromone side of the hangers 16 to the other and theirmovements will carry the back 21. Thus, as shown in Figs. 3 and 4, theseat may be reversed and positioned at either side of the hangers and ineither position the seat will be firmly supported by engagement of thelates' 24 with the stops 28. Moreover, the p ates 24 constitute frictionelements between the arms 23 and the hangers 16. When the swing is notrequired for use the legs 10 may be folded one within the other and thehangers 16 Within the plane of the legs. Also, the complete seat may befolded into a vertical position within the plane of the legs as shown inFig. 2 in which position the friction plates 24'will'sustam the seat.

As is well known the spread legs of the 7 swing constituting thesupporting. frame tend to shift under the action of the swing,

there being a shifting force exerted on the forward legs by the forwardmovement of the swing and a similar ace-011011 the rear legs in therearward movement of the swing.

To prevent shifting or creeping of the legs I provideresilient bufferblocks 29 preferably of rubber. The under side of each block is beveledor inclined so that one end of the block forms abearing terminal, and aclearance space is presented extending from said end toward the oppositeend.

Usually, the beveled surface is produced by.

forming the blocks of reduced thickness at one end, the uppersurface'being hor zontal to mate the horizontal under surface of theleg. The blocks are' reversed on the front 7 and back legs so that thebearing terminals thereof of the front legs w'illbe at the front and thebearing terminals of the rear legs will be at the rear. The shocksto'which the front legs are subjected by the swing by a forward movementthereof will'compress the front blocks, increasing the gripping actionor the front ends thereof, the

front end thereof to swingto a position at eitherside of the hangers orafposition'betweenfthe' h'angers'and in the plane thereof, a backpivoted at its lowerend to the.

rear end of the said seat, arms pivoted at the front ends thereof to thehangers at the inner faces of the latter above the seat pivots, the saidarms being adapted to swing to either side of the hangers or to anintermediate position in the plane of the hangers, the rear ends of saidarms being pivoted to the upper end of the said back, saidback beingswingable with the seat and arms to either side of the hangers or to aposition in the plane of the hangers, stops on the hangers at the; innersurfaces thereof beneath'thepivots of the arms, and plates interp'osedbetween the outer faces of the arms and: the hangers and swingable withthe arms withith'e adjacent pivot s' ofthe arms as axes, the said platespresenting ends proj ecting beyond the upper and lower'surfaces of thearms when the seat is in position for pivots, the said arms beingadapted to use, the said projecting ends presenting edges either ofwhich is engageable with thefiXBd stops on the hangers to sustain theseat at either side of the hangers.

2.111 a swing, hangers, means mounting the hangers for swingingmovement, a sent between the hangers and pivoted near the front endthereof to swing to a position at either side of the hangers or aposition between the hangers and in the plane thereof, a back pivoted atits lower end to the rear end of the said seat, arms pivoted at thefront ends thereof to the hangers at the inner faces of the latter abovethe seat swing to either side of the hangers or to an interi'nediateposition in the plane of the hangers, the rear ends of .said arms beingpivoted to the upper endof the said back, said back being swingable withthe seat and arms toeither side of the hangers or'to a position in theplane of the hangers, fiXed stops on the hangers adjacent to the pivotsof the arms, and oppositely disposed stop members on each arm, one ofthe stop members of each arm being engageable with the fixed stop tosustain the seat positioned at either side of the hangers.

3. In a swing, a support, hangers swingable'on the support, a foldableseat struc tureiincluding a seat, side arms, and a back pivotallyconnected with the seat and arms, said seat and arms being pivoted tothe hangers to be positioned at either side thereof,'a fixed stop oneach hanger and a stop rigid with each side arm to turn therewith, eachof said stops, when the seat is in position for use, presenting lateralsurfaces above and below the adjacentpivot of the arm an'd'disposedtoward the fixed stop $0 that either of the said surfaces ofeach stopwill engage the adjacent fixed, stop as the seat is positioned at oneside or the other ofthe hangers.

4:. In a swing, a support, hangers mounted' to swing on" the support, aseat between the hangers and pivoted near the front end thereto, sidearms above the seat and pivoted near the front ends to the hangers, a

back pivotally connected at its lower end with the seat and at its upperend with the side arms, said seat, arms and back being swingable fromone side of the hangers to the other, and co-acting stop elements'on thehangers and side arm s engageable with each other when the arms aredisposed at either side of the hangers.

5, In a swing, a support, hangers mounted to swing on the support, aseat between the hangers and pivoted near the front end thereto, sidearms above the seat and pivoted near the front ends to the hangers, aback pivotally connected at its lower end with the seat and at its upperend with the s1de arms, said seat, arms and back being swingable fromone sideof the hangers to the other, a fixed stop on each hangerben'eath the pivots of the side arms, plates between the side arms andhangers, the adjacent pivots of the arms passing through said plates,and means rigidly fastening the saidplates to the side arms, said platespreside of the hangers, either of said members 10 being adapted toengage the fixed stops on the hangers according to the position of thearms at either side of the hangers.
